Jenny Shank is right.
Our vaguely national park-ish "Welcome to Colorful Colorado" signs "evoke mountain lodges, cabins, and the beloved Western bears Yogi and Smokey."
OK, I might question the last, since I always assumed that Jellystone Park, like Yellowstone Park, was in Wyoming.
But her basic point is sound. The other day, I saw that one of the older motels in Salida, Colorado, advertised itself as "retro." Let's keep our retro welcome signs.
